Temporary tattoos

 Temporary tattoos are popular with models and children as they involve no permanent alteration of the skin but produce a similar appearance that can last anywhere from a few days to several weeks. The most common style is a type of body sticker similar to a decal, which is typically transferred to the skin using water. Although the design is waterproof, it can be removed easily with oil-based creams. Originally inserted as a prize in bubble gum packages, they consisted of a poor quality ink transfer that would easily come off with water or rubbing. Today's vegetable dye temporaries can look extremely realistic and adhere up to 3 weeks due to a layer of glue similar to that found on an adhesive bandage. Henna tattoos (Mehndi) and silver nitrate stains that appear when exposed to ultraviolet light can take up to two weeks to fade from the skin. Silver nitrate is, however, a toxic substance and should not be used on skin. Temporary airbrush tattoos (TATs) are applied by covering the skin with a stencil and spraying the skin with ink. In the past, this form of tattoo only lasted about a week. With the newest inks, tattoos can reasonably last for up to two weeks. Airbrush Tattoos are mostly all sprayed with cosmetic paints now. They are getting to be more popular because of the ease in removing them. Unlike henna tattoos, the cosmetic paints can be rubbed off with isopropyl alcohol.
